When driving doubles or triples around a curve, you should:

a.Drive at the posted speed limit for the curve

b.Drive slower than the posted curve speed

c.Drive slightly faster to maintain momentum

d.Accelerate through the curve to stabilize the trailers

Explanation

Safe curve speeds posted for single vehicles may be too fast for doubles and triples. Due to the higher center of gravity and rearward amplification, you should always drive slower than the posted curve speed to prevent rollovers.
